1. Take a roll of small adhesive tape and repeatedly stick the sticky side to the tattoo sticker on the skin. You can use the viscosity of the adhesive tape to stick the tattoo sticker off the skin.

2. Dip a small amount of nail polish remover with a cotton pad or cotton swab and cover it on the tattoo sticker. When nail polish remover wets the sticker, wipe it off with a cotton pad after a few minutes.

3. Dissolve the stickiness in the tattoo sticker in alcohol, soak the tattoo sticker on the skin surface in alcohol, and then wipe it off with cotton cloth after waiting for a few minutes.
